Abstract
Accuracy of Global Navigation Satellite System (GNSS) for GNSS devices is improved using a GNSS positioning system that leverages networked optimization for enhanced accuracy. GNSS measurements from multiple devices form the foundation for a massive pairwise optimization approach. This fuels a self-reinforcing cycle, wherein Real Time Kinematic (RTK) pairwise optimizations support Precise Point Positioning (PPP) analysis. Improved PPP calculations in turn refine RTK optimization, rapidly iterating towards convergence. The PPP-RTK feedback loop refines positions iteratively, culminating in more accurate user locations.
